French authorities on Wednesday detained two suspects over a heist at a high-end Paris boutique by an armed robber who fled the scene on an electric scooter, according to local media.
Local broadcaster BFMTV reported French authorities had recovered most of the $2 million worth of jewelry stolen from a Chaumet store in central Paris.
Citing sources close to the investigation, BFMTV said two suspects were detained at a motorway rest area near the city of Metz, close to the French border with Germany.
There was no immediate confirmation from French police.
A CCTV image from the scene showed a man, identified by the broadcaster as the suspected robber, in a grey suit inside the store.
Local media reported he calmly presented himself to staff as a customer, and asked to view some jewelry, before pulling out a handgun, grabbing the jewels, and leaving the store.
Another CCTV image broadcast by BFMTV showed what looked like the same man, riding a stand-up electric scooter down the street, with a white bag hanging from the handlebar of the scooter.
Chaumet is one of France's oldest jewelry brands and is owned by luxury goods conglomerate LVMH.
